I have carried the same SAK since 1991 when I got it at an Eddie Bauer Store in Tulsa Oklahoma with a coupon I won from a sales contest for my company. Its a Wenger SAK. I got it because it had everything on it that I wanted and I had never seen one before or since with all the same tools this one has. It came with pliers, phillips screwdriver instead of the cork screw, serrated scissors, leather punch, bottle opener/screwdriver/wire stripper that is a locking blade when you push on it using the flat head screwdriver, can opener, fingernail file, and locking main blade and a pretty aggressive and capable saw blade. Of course it has the tweezers and tooth pick also.
The original red handle scales came off years ago and I had my friend Dirk (AKA Oupa) put some fiddleback maple scales on it in their place. He has breathed new life into many SAKs in his day and mine is a very good example of his expertise. It looks better than new and still sees duty everyday. The main reason I love this SAK besides my friends personal touch is for the serrated scissors. They simply do not dull. I use them for cutting everything from gun cleaning patches to old credit cards. I also love the pliers which are actually pretty darn handy.
